I walked along the sidewalk with two other moms I’d recently met, three astride, our newborn babies in strollers in front of us. A jogger approached from the other direction, but none of us made a move, expecting her to go around us on the grass. “You could get out of the way,” she snidely snipped as she passed. I felt bad for our lack of consideration, but one of the moms said, “You never know, maybe she can’t have kids and is taking it out on us.” The other mom agreed, but they didn’t know “us” didn’t really apply to me.
